/* @test

 * @bug 4322806

 * @summary When an RMI (JRMP) connection is made to a TCP address that is

 * listening, so the connection is accepted, but the server never responds

 * to the initial JRMP handshake (nor does it terminate the connection),

 * the client should not hang forever; instead, it should throw an exception

 * after a reasonable timeout interval.  The exception should be a

 * java.rmi.ConnectException or ConnectIOException, not a MarshalException,

 * because it should be clear that no partial call execution has occurred at

 * this point (because no data for the invocation has yet been written).
